The relationship has been going for 11 months now. Spend every weekend together and keep in phone contact 2-3 times a day during the week.
This past month I have noticed my partner becoming increasingly cold. His evening phone calls were once a fun recap of his day and enquiring about mine but have recently been reduced to pretty much "I'm fine, tired, I can't talk long as I want to go to bed early. We'll catch up in person at the weekend". Of course, we're all occasionally tired and I would understand this but this has been a huge and sudden change in behaviour. I'm not normally someone who enjoys talking on the phone but he established these nightly calls initially and they've become a part of my routine.
At weekends when we're together I've noticed him becoming a little distant. He doesn't work Fridays so he used to arrive at mine as soon as I got home. Lately he's arriving later and later, sometimes after 8:00pm when I've been at home hours. On Sundays he used to stay until about 6:00pm before leaving for home but I now see him looking at his watch like he's counting the minutes until he can leave. He seems distant and to not really look forward to seeing me anymore.
These past three weekends he's cancelled our plans. The first time he was ill (although he later mentioned that he'd visited friends for coffee and a catch up that weekend). The second he was tired after a long week and didn't feel like was in the mood to see me (once again he later mentioned having gone to see friends). I missed him horribly but in the interest of keeping the peace I stayed quiet. This past Friday he sent me a morning message telling me he couldn't wait to see me. I spent the day cleaning, changing bed sheets, and cooking him his favourite meal. He rang at 5:00pm and said he'd be a little late as he had a work phone call to make. He asked about food and I told him it was all taken care of and would be ready for his arrival. He rang again two hours later to tell me that his work phone call had left him "weary" and he wasn't "in the mood" to see me until the next day.
I asked him were we okay to which he replied "Yes, I'm just tired". He seemed to think it was a silly question. I was very angry and just about managed to not snap at him. I told him that his tiredness has been going on for at least a month and that I didn't want to see him this weekend at all. He replied "If it's that big a deal I'll come and see you tonight". I told him to go and visit his friends and told him not to visit as I need time to calm down.
I later sent him a long text explaining that I have recently noticed a big shift in his behaviour and that he now seems to need more and more time alone. I scolded him for allowing me to cook and clean for him only to cancel at the last moment. I suggested that we stop all contact for the next week and that he take that time to have a good long think about whether he even wants to be in this relationship at all. I didn't shout but I made him aware that I felt he was taking our relationship for granted and not prioritising our time together. I told him that we could meet for a walk this Friday and talk about whether he wants to go forward together or not.
It's been two days of total silence and all I've received is a text from a friend of his accusing me of trying to emotionally black mail by using the "silent treatment". I sent a very short reply telling his friend to not contact me about private business again.
Am I in the wrong for needing time to calm down and giving him time to think about whether he even wants to be in this relationship?
